Blade pitch stall margin

The Robinson R22 flight manual states the blade pitch is near stall at higher gross weight. Also the NTSB special report on the R22 accident history dicusses the high blade pitch of the Robinson as a possible cause of the several dozen rotor separation incidents.
My question is: what is the blade pitch of a R22 in hover and cruise and what is the blade pitch of other helicopters. Is it normal to run close to blade stall?
